Agent, liquid, and method for cleaning reverse osmosis membrane |
| abstract |
Provided is an agent and a liquid for cleaning an RO membrane to remove effectively foulants that can not be sufficiently removed with conventional cleaning agents when an RO membrane particularly an aromatic polyamide RO membrane has been used for water treatment and has become fouled resulting in degradation of performance such as permeation flux, pressure difference, and salt rejection rate. The agent for cleaning an RO membrane includes an aliphatic amide and/or an aromatic amide. Also provided is a method for cleaning an RO membrane with the cleaning agent or the cleaning liquid. The aliphatic amide and/or the aromatic amide particularly an aliphatic amide and/or an aromatic amide being soluble in water and having a relatively low molecular weight remove effectively foulants adhered on an aromatic polyamide RO membrane. |
